RBLTracker supports an IP Range Host type, which lets you add hosts as:
- CIDR ranges – for example, 10.10.10.1/24 to add a full class C.
- IP lists either as 10.10.10.10 – 10.10.10.15 OR 10.10.10.10-15 to add a the range of 6 addresses.
Rather than each individual IP address showing up under your list of hosts, you’ll see a single IP Range entry in your hosts list, and can be managed as a single entry.
All individual IP addresses in the range are monitored and billed for separately, but are managed as a single host entry, making it easier to manage large IP blocks.
You can also add ranges of IPv6 addresses. For example, 2600:118:49:5300:75:48:46:708/125 would add as a block of 8 IPv6 IP addresses.
